Extended Data Fig. 6: Distance decay function.
From: Extreme geographic misalignment of healthcare resources and HIV treatment deserts in Malawi
The distance decay function is shown in orange. It shows the relationship between travel time and the ‘exceedance probability’, that is, the cumulative proportion of communities that can reach a HCF in a certain travel time (or longer). The distance decay function was estimated by fitting a logistic function through data (blue) on the travel times between each community and the nearest HCF (Residual Sum of Squares, RSS = 0.0019).
